NI'IED STATES FFIoE;

IMPROVEMENT IN .ENVELOPES.

Specification forming part of Letters Patent No. 183,380, dated October17, 1876; application filed August 10, 1875.

To all whom it may concern:

Be it known that I, EDWARD DQDOUGH- ERTY, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedEnvelope; and'I do hereby declare that the following is a full, clear,and exact description of the same, reference being bad to theaccompanying drawing, forming a part of this specification, in whichFigure l is a plan view of the blank. Figs. 2 and 3 are plan views,respectively, of the back'and face of the envelope.

The invention is an improvement in the class of envelopes one end ofwhich projects beyond the body or part for containing the letter proper,to form a margin to which the stamp may be afiixed, and whereon it maybe canceled without risk of injury to the letter or other contents ofthe envelope. The invention relates particularly to the construction ofthe envelope-blank for forming such margin, as hereinafter described.

A A represent the long rectangular body of envelope, having the shortfolding side flaps B 0, end flap D, and fold a at ends of these sideflaps. The part A extends from fold a, back over and beyond the part A,havin g a return-flap, E, that turns at the fold a, and is pasted to theflaps O D, thus forming a cavity for the letter, and a separate sideextension, F, for the postage-stamp.

The stamp may be then' canceled by cutting, pricking, tearing, or in anyother manner, without affecting the contents of the co velope.

Having thus described my invention, what I claim as new is- Thecombination, with the long rectangular strip AA, of the turn-flaps B O Dand return-flap E, to form the envelope, with extension F, in the mannerspecified.

EDWARD D. DOUGHERTY.
